Stronger Evidence Favors Mediterranean Diet

A new study may provide the best evidence yet that a Mediterranean-style diet reduces people’s risk of heart attack and stroke. Unlike previous studies, the new one randomly assigned 7,500 people to specific diets. They followed the diets for 5 years. In that time, people on Mediterranean diets had a 30% lower combined rate of heart attack, stroke and deaths from related causes. Considered separately, only the stroke rate reduction was large enough to be clearly not the result of chance. Everyone in the study had a high risk of developing heart disease or stroke. Nearly all were overweight or obese. Most had high blood pressure and high cholesterol. About half had diabetes. Two groups were randomly assigned to a Mediterranean diet. This included lots of fruits, vegetables, whole grains, tomato sauce, fish and legumes.
